DOOB-CONTROLLING DE VICE Specification of Letters Patent.

Patented March 80, 1909.

Application filed October 21, 1908. Serial No. 458,902.

To all whom 'it may concern.:

Be it known that we, THOMAS KUsH and ARTHUR WEBBER, citizens of theUnited States, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inDoor-Controlling Devices, of which the following is a specification.

Our invention relates to doorfchecks and the chief objects of theimprovements which form the subject matter of this a plication arez-toprovide a simple and ef cient device for limiting the movement of a doorto its open osition and to furnish means for relieving t e shock uponlthe ordinary door check when the door reaches the limit of itsmovements.

Other important advantages of the cushioning and controlling meansherein shown are seen in the tensioning device which pre- I vents anyslackin the traction member, ex-

erting a constant tension thereon, and in addition acting as a closurefor the door, the latter function adapting the device to be used as anauxiliary to the ordinary pneumatic door-closing check, though it may beemphyed without any such cooperating device. urther objects of thisinvention are to furnish a means for reversing the contrivance to adaptit for use on either right or left-hand doors, and a swivel devicepermitting variations to be made in the relative positions of theattachments at the opposite ends of the traction member and to preventthe latter from twisting and thus reventing it from entering the casingrovi( ed therefor.

We accomplish t e desired results b the means illustrated in theaccompanying rawin forming a part of this application, the deta s ofconstruction being disclosed in the following views Figure 1 is apartial view of a door and framey showing our improved door checkcontroller erected in operative relation; Fig. 2 is a bottom plan viewof the door-frame attaching plate, the casing and parts arranged thereinbeing partly in section; Fig. 3 is a sectional view on the line 3-3 ofFig. 2 Fig. 4 is a side elevation ofthe frame plate and casing with thetraction member removed; Fig. 5 is a side elevation ofthe spool or reel;Flg. 6 is a side view of the traction member and lts door attachment,and Fig. 7. is an ed e view of the arts shown in Fig. 6, the swivemember be- 1n in section.

eferring to the details of the drawing the numeral 10 indicates thelintel of a door frame and 11 the u right hinge edge of the door casing,to whic the door 12 is hinged, only a ortion of the latter being shown.Fastene to the under face of the lintel 10 is a base plate 13, securedby screws which pass through holes 14. One end of this plate is suppliedwith an annular retaining flange or ring 15, which forms a socket toreceive the end of a cylindrical casing or shell 16, having end platesor heads 17, secured thereto by screws 18. This casing or shell isattached by suitable screws 19 which ass through the base plato 10 andengage ho es 2O in the casing ends. The peripheral wall of the casing isprovided with a rectangular aperture 21 for the passage of the tractionmember 29 hereinafter described. 'lhis arrangement permits the casing tobe reversed so that it may be assembled with either end or face againstthe base plate, and within the retaining lange 15, thus adapting it foruse with doors opening in opposite directions. lVithin the casing andconcentric therewith is revolubly mounted a spool or reel 22, havingwidel f extending llanges o1' end plates 23. Tie reel ismounted Vto turnon a central shaft 24, which projects through each plate 23. The ends ofthe shaft are reduced where they pass through the plates and theextremities are squared as shown at 25, to engage corresponding holes inthe casing end plates or heads 17 thus preventing the shaft fromturning. lithin the cavity of the spool body is arranged a spirallywound ribbon or clock spring 26, having its inner and outer endsfastened to the shaft 24, and the wall of the body, respectively, asshown at 27, and 28. Ada ted to be wound upon the said reel or spoo 22is a flat leather or flexible stra 29, having its inner end attached t0a bo t 30 supported in the flanges 23, (see Fig. 5). The strap thenpasses through the aperture 21 in the casing and is formed at its outerend into a loop 31, which engages an eye or stale 32, of a block 33,attached to the end of a liolt 34. Surrounding this bolt is acylindrical sleeve 35, fitted at one end with a removable threaded plug36, through which the said bolt 34 projects, and between the head 37 ofthe bolt and said plug is a coiled compression sprin 38: The end of thesleeve opposite tie p u 1s formed with an extension 39 ivoted y a rivet40- between ears 41, of b ook 42, the latter having holes 43 for screws44 by which it is attached to a I casing, .a spring for rotating thereel in one door. The bolt 34, shell 35 and interposed spring 38 form ayielding and swivel connectlon between stra and door which -permits theattachment o the block 42 to a door in any desired osition relative tothe other parts and at t e same time the spring 38 acts as a bufler torelieve the shock on the spring 26 when the strap is unwound the maximumlimit.

The manner of attaching our improved door check controller will beclearly understood by reference to the assembled view, Fig. 1 The baseplate with the, casing in place is screwed to the-under side of thelintel, e. near the edge opposite to\the side upon which the door ishung, and the plate 42 is secured to the door near the u per edge, at aoint corresponding with the ocation of the ase plate when the door isclosed. Care, of course, must be taken when assembling the reel 22Within the shell 16, so that the spring 26 Will be under a sufficientamount of tension when the strap 29 is completely wound upon the reel,to urge the door into its closed position and fully wind up the strap.

With the parts assembled as illustrated it will be plain that when thedoor is closed the action of the clock spring 26 which is partiallywound up will wind the strap 29 upon the reel, and as the door is openedthe traction of the said strap will turn the reel in such a direction asto completelywind up the spring. The length of the strap is soproportioned that when the door is at its maximum o en position the saidstra will be completely unwound from the ree and will extend 1n astraight line between the bolt 34 and the pinBO. Upon the release of thedoor, the action of the clock spring will cause it to close, and thestrap will be Wound upon the reel Without becoming slack. The device isshown in Fig. l attached to door hung left handed. To adapt the ap"liance to a right-hand door the shell 16 is iist removed by looseningthe screws 19, and then reversed and secured with the opposite face orhead in the socket ring or iiange 15, by the same screws, and the plateattached to the lintel in the manner described.
